Description

Mooring rope protection device of ship}

The present invention relates to a device for protecting the no-ring rope of a ship, and in particular, an improved ship that can securely protect the no-ring rope for ship anchorage and achieve a long life by implementing a choke liner as an integral type of soft plastic and using it in combination with a choke. It relates to a mooring rope protection device

In general, a fairlead is a guide member that is installed on all of the bow, stern, and side of a ship and guides the mooring line (towing rope or chain) of a towing device used for berthing, anchoring, or towing of the ship.

In addition, the mooring line is connected to the tugboat by connecting from the towing device or the berthing device installed on the freeboard deck, or it is connected to a cylindrical pile-type fixing part fixedly installed in a port or terminal.

As techniques related to such fairleads, Korean Patent Publication No. 2009-0105101, Registration Patent No. 1185399, and Publication No. 2014-0006023 are disclosed.

On the other hand, a typical fairlead is in the form of a choke.Since such a choke is mainly made of castings, the surface is not smooth, causing extreme damage to the traction rope during friction.Also, the paint applied to the choke itself peels off, reducing the lifespan due to rust. There is also a drawback that causes it.

Accordingly, as a solution to this disadvantage, there is an example of preventing damage to a traction rope, that is, a mooring rope by embedding a choke liner as in the following [prior art literature] in a choke.

In addition, as described above, a typical choke is made of a casting and is not processed, so its dimensions and surfaces are not uniform.

Therefore, when a choke liner made of hard plastic is installed on a choke, if the surface of the choke is not uniform, an empty space is generated at an unspecified location, and additional work is required to fill it.

If the empty space between the choke liner and the choke is left unattended, the choke liner is likely to be damaged if force is applied from the rope.

However, even when trying to fill an empty space at an unspecified location, it is difficult in reality because it cannot be confirmed with the naked eye.

In particular, if the dimensions are not correct, the assembly may not be possible and correction processing may be required, or there may be cases in which it is not closely adhered or fixed to the choke due to the overall looseness.

In addition, there is a vulnerability in that the friction force generated by the contact surface with the choke is weak due to the characteristics of a plastic chokeliner made of a hard material when moving due to force applied to the rope, causing a lot of force to escape. And, if it is loose as a whole, there is a problem of separation and damage.

For this reason, additional work such as a separate bonding treatment to increase the adhesion and fixed friction of the hard material plastic choke liner is inevitable.

In addition, in the method of assembling by bolts of a plastic chokeliner made of a hard material such as [prior art literature], it is difficult and dangerous to assemble and disassemble as the divided one is necessarily inserted into the choke from the outside of the ship.

In addition, the assembly method using such a bolt is made thick to prevent damage due to the nature of the material, so it is difficult to work with manpower due to the thickness and weight.

The present invention was created to solve the problems in the prior art as described above. By implementing a chockliner as an integral type made of soft plastic and using it in combination with a choke, it safely protects the no-ring rope for ship anchorage and increases its lifespan. Its main purpose is to provide an improved protection system for the ship's no-ring rope to achieve

The present invention is a means for achieving the above object, and is installed in the inner space of the choke in the ship's no-ring rope protection device including a choke made of castings installed on the deck of a ship and a no-ring rope passing through the choke , The choke liner is interposed between the choke and the choke to eliminate direct friction between the choke and the choke, but the choke liner is molded of soft plastic and formed integrally so that it can be pressed into the inner space. It provides a device for protecting the no-ring rope of a ship, characterized by.

In one embodiment, flanges are further formed around both ends of the choke liner to be hooked to the front and rear ends of the choke, and are cut along a cutting line in the longitudinal direction of the choke liner.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

Prior to the description of the present invention, the following specific structure or functional descriptions are exemplified only for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as being limited to the embodiments described herein.

In addition, since embodiments according to the concept of the present invention can be modified in various ways and have various forms, specific embodiments are illustrated in the drawings and will be described in detail in the present specification. However, this is not intended to limit the embodiments according to the concept of the present invention to a specific type of disclosure, and it should be understood that all modifications, equivalents, and substitutes included in the spirit and scope of the present invention are included.

The present invention is invented by the difference between the choke and the choke liner supplier, and the need for a choke liner that meets all of the characteristics of the casting production of the choke, and the choke liner made of soft plastic has good elasticity and It is conceived that even if the surface is not uniform, it can be adhered to during installation, and even if it is subjected to force by a rope, it is adhered to the surface by its unique elasticity to prevent damage due to empty spaces.

In this case, designing a small protrusion shape in the form of fine irregularities on the contact surface of the choke liner in contact with the choke can further maximize the contact force due to friction.

In addition, the soft material plastic chocliner can be installed and removed from the inside of the ship, so it is easy to work and is not dangerous. In other words, it is manufactured as an integral type rather than a bolt assembly method, so that the thickness is thin and light, so it is possible to work easily with manpower.

As shown in Figs. 2 to 4, the apparatus for protecting a non-ring rope of a ship according to the present invention includes a choke 100.

At this time, the choke 100 is made of a casting as in the past, and has an inner space 110 formed in a saddle shape. Of course, the inner space 110 is generally a space through which the Mourning rope passes.

However, in the present invention, a chock liner 200 is fitted in the inner space 110. Through this, the choke liner 200 is located between the mooring rope and the choke 100 so that the mooring rope does not come into direct contact with the surface of the choke 100 made of a cast, thereby suppressing acute wear of the mooring rope and increasing its lifespan. Induced.

Conventionally, a choke liner has existed, but the conventional choke liners are all detachable and are bolted to each other in the inner hole 110 after being inserted into the inner space 110 from the front and the rear with the choke 100 interposed therebetween.

Therefore, although the problems mentioned in the prior art were inevitably derived, the present invention has the biggest difference in that the chocliner 200 is configured as an integral type rather than a separate type.

In particular, the chocliner 200 is formed of a soft synthetic resin and is integrally molded, and then the end is bent and passed through the inner space 110 by inserting it into the inner space 110 as illustrated in FIG. 4, and then the bent one is released and unfolded. Can be assembled.

Here, the meaning of bend means that a group of apertures are squashed to have a size that can be inserted into the inner space 110.

This is possible because the choke liner 200 is molded from a soft synthetic resin, and above all, flanges 210 are formed at the front and rear ends of the choke liner 200 so that the front and rear ends of the choke 100 are elastically Because it adheres closely.

Therefore, the choke liner 200 according to the present invention may be manufactured in various sizes according to the size of the choke 100, and in some cases, cut along the cutting line 220 in the longitudinal direction as in the example of FIG. After the cut ends are folded in an overlapping form and inserted into the inner space 110, and then when the overlapped part is released, the external force is removed and the choke liner 200 is opened by the elastic return force, and the inner space of the choke 100 ( 110) in close contact with the cutting lines 220 to each other, very easy and complete assembly and installation is possible.

In this case, the cutting line 220 is preferably arranged on the upper side so as not to interfere with each other when the mooring rope moves.

In addition, in the present invention, it is preferable to use a polyurethane resin containing 5.5-7.5% by weight of PTFE (polytetrafluoroethylene) so that the chocliner 200 has ductility while securing lubricity and wear resistance. In this case, it is better to treat the surface of the molded article with fluorine coating.

Here, the PTFE resin is a strong, tough and smooth non-flammable resin belonging to an organic polymer series consisting of large molecules made by chemically bonding many small molecules (units) in the form of chains or nets, and is added to the polyurethane resin. In addition to securing lubricity, it enables consistent lubrication without viscosity change within the range of -50℃ to 350℃.

In addition, the polyurethane resin is a base resin, and its basic properties are rich in elasticity, good elasticity, strong and tough, and have high tensile fracture strength.It is also suitable as the base resin of the present invention because it has excellent wear resistance, aging resistance, and oil resistance.

And, the reason for the fluorine coating is to maintain the ductility of the chocliner 200, but to increase the hardness on the surface to enhance abrasion resistance, and to reduce the frictional force to reduce the abrasion resistance of the no-ring rope.

Through this, it is possible to achieve a longer life of the mooring rope, and conversely, it is possible to obtain the advantage of significantly reducing the damage to the chocliner 200.

6 is a view showing a protrusion line for engaging formed in the chocliner shown in FIG.

5 and 6, the flanges 210 formed at the front and rear ends of the choke liner 200 in FIG. 5 have a structure that is hung in a direction perpendicular to the front and rear ends of the choke 100. However, the flange of the choke liner 200 in FIG. 6 is provided with a protrusion line 230 for engaging a shape that completely surrounds the rear edge of the choke 100.

Therefore, as the locking protrusion line 230 completely wraps the rear edge of the choke 100, even if the Mouring rope moves through the inside of the choke liner 200, the choke liner 200 is stably attached to the choke 100 It can be tightly fixed and can be prevented from leaving.

On the other hand, when the choke 100 and the choke liner 200 are in contact, as a plurality of friction protrusions are formed on the contact surface, adhesion through greater friction can be maximized, which will be described in more detail with reference to FIG. 7. .

7 is a view showing a plurality of friction protrusions formed on the outer surface of the chocliner shown in FIG.

Referring to FIG. 7, one or more friction protrusions 200a are formed at regular intervals in a region of the outer surface of the choke liner 200 in contact with the choke. Through this, the adhesion with the choke can be maximized through friction by the friction protrusions 200a protruding at regular intervals.

In addition, an embodiment of the present invention proposes a method of more strongly fixing the choke liner 200 to the choke 100 by using a fixing rope. This will be described in more detail with reference to FIG. 8.

FIG. 8 is a diagram illustrating a state in which the choke liner is bound and fixed to the choke by a plurality of through holes perforated in the choke liner shown in FIG. 5 and a rope rope.

Referring to FIG. 8, a plurality of through holes 200b facing the longitudinal direction of the choke 100 are perforated in both flanges 210 of the choke liner 200 of the present invention.

At this time, the through-holes 200b perforated in each of the flanges 210 are symmetrical to each other, and the choke liner 200 is fixed to each of the plurality of through-holes 200b while being installed in the inner space of the choke 100 When the rope 200c penetrates and is bound, the choke liner 200 is completely bound to the choke 100. Therefore, even if the Mooring rope moves while being strongly rubbed against the inner surface of the chocliner 200, the chocliner 200 may be strongly bound and fixed to the choke 100 by the binding force of the fixed rope 200c.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. You will understand that you can.

100: choke
